All known Subclasses: com.sleepycat.collections.StoredSortedValueSet,
| StoredValueSet | | public class StoredValueSet extends StoredCollection implements Set(Code) | | The Set returned by Map.values() and Map.duplicates(), and which can also be
constructed directly if a Map is not needed.
Although this collection is a set it may contain duplicate values. Only if
an entity value binding is used are all elements guaranteed to be unique.

| Method Summary | |
| public boolean | add(Object entity)
Adds the specified entity to this set if it is not already present
(optional operation).
This method conforms to the
Set.add interface.
Parameters:
entity - is the entity to be added. | | public boolean | contains(Object value)
Returns true if this set contains the specified element.
This method conforms to the
java.util.Set.contains interface.
Parameters:
value - the value to check. | | boolean | hasValues()
| | Object | makeIteratorData(BaseIterator iterator, DatabaseEntry keyEntry, DatabaseEntry priKeyEntry, DatabaseEntry valueEntry)
| | public boolean | remove(Object value)
Removes the specified value from this set if it is present (optional
operation).
If an entity binding is used, the key-value pair represented by the
given entity is removed. |
| StoredValueSet | | public StoredValueSet(Database database, EntryBinding valueBinding, boolean writeAllowed)(Code) | | Creates a value set view of a
Database .
Parameters:
database - is the Database underlying the new collection.
Parameters:
valueBinding - is the binding used to translate between valuebuffers and value objects.
Parameters:
writeAllowed - is true to create a read-write collection or falseto create a read-only collection.
throws:
IllegalArgumentException - if formats are not consistentlydefined or a parameter is invalid.
throws:
RuntimeExceptionWrapper - if a DatabaseException isthrown. |
| StoredValueSet | | public StoredValueSet(Database database, EntityBinding valueEntityBinding, boolean writeAllowed)(Code) | | Creates a value set entity view of a
Database .
Parameters:
database - is the Database underlying the new collection.
Parameters:
valueEntityBinding - is the binding used to translate betweenkey/value buffers and entity value objects.
Parameters:
writeAllowed - is true to create a read-write collection or falseto create a read-only collection.
throws:
IllegalArgumentException - if formats are not consistentlydefined or a parameter is invalid.
throws:
RuntimeExceptionWrapper - if a DatabaseException isthrown. |
| add | | public boolean add(Object entity)(Code) | | Adds the specified entity to this set if it is not already present
(optional operation).
This method conforms to the
Set.add interface.
Parameters:
entity - is the entity to be added. true if the entity was added, that is the key-value pairrepresented by the entity was not previously present in the collection.
throws:
UnsupportedOperationException - if the collection is read-only,if the collection is indexed, or if an entity binding is not used.
throws:
RuntimeExceptionWrapper - if a DatabaseException isthrown. |
| contains | | public boolean contains(Object value)(Code) | | Returns true if this set contains the specified element.
This method conforms to the
java.util.Set.contains interface.
Parameters:
value - the value to check. whether the set contains the given value. |
| hasValues | | boolean hasValues()(Code) | | |
| remove | | public boolean remove(Object value)(Code) | | Removes the specified value from this set if it is present (optional
operation).
If an entity binding is used, the key-value pair represented by the
given entity is removed. If an entity binding is used, the first
occurrence of a key-value pair with the given value is removed.
This method conforms to the
Set.remove interface.
throws:
UnsupportedOperationException - if the collection is read-only.
throws:
RuntimeExceptionWrapper - if a DatabaseException isthrown. |
